    If \[\text{CL}=\text{a},\]then find o In terms of x, y and d.

    A) \[\frac{xd}{z}\]

    B) \[\frac{xz}{d}\]

    C) \[\frac{zd}{x}\]

    D) \[xzd\]

    Correct Answer: C

    Solution :

    \[\Delta CAB\tilde{\ }\Delta CLO\]
    \[\therefore \,\,\,\,\,\,\,\,\,\,\frac{CA}{CL}=\frac{AB}{LO}\]
    \[\Rightarrow \,\,\,\,\,\,\,\,\,\,\frac{z}{a}=\frac{x}{d}\,\,\,\,\,\,\,\,\,\Rightarrow \,\,\,\,a=\frac{zd}{x}\]
    So, option [c] is correct.
